WATER-COO LING TOWER.

SPECIFICATION forming part of Letters Patent No. 697,160, dated April 8, 1 902.

Application filed October 7,

1901. Serial No. 77,788. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM OSTENDORFF', a citizen of the United States, residing at Union Hill, New Jersey, have invented certain new and useful Improvements in Water- Cooling Towers, of which the following is a specification.

My invention relates to that class of watercooling towers wherein the temperature of the water is'reduced by causing it to fall through the air from a height in the form of drops or sprays; and my present improvements consist in certain for preventing the falling spray from being driven out of its proper course by abnormal drafts of air.

I will now proceed to my improvements, and in so doing I will refer to the accompanying drawings, wherein- Figure view of a watercooling tower embodying my improvements; and Fig. 2 is a perspective view of one of my improved spraying-pans, a portion of one side of the pan being broken away on the line was to show the details of construction and a corher of the pan being broken away at 1 to show the wooden reinforcing thereof.

7 which maybe reinforced within with a wooden strip to stiffen the edges of the pan. The bottom of the pan is likewise formed of sheet metal,- which is bent or crimped into the my improved tower is flanges D D D, and the bottom of the pan above these inclined flanges is perforated, as at e e e. The water falling into the pan will pass through the perforations e e e and falling upon the deflecting-flanges D D D will be spread and deflected and fall from the edges of the flanges in drops or spray, as described in my previous application. By constructing the bottom of the pan with flanges integral therewith I am enabled to secure a stifier bottom than one in which the flanges are riveted or otherwise secured to the bottom, and I also avoid weakening the bottom by punching rivet or bolt holes through it, which when galvanized material is used are apt to present raw surfaces to be corroded by the action of the water. I

These towers for cooling water by atmospheric evaporation are preferably placed in positions where there is an abundant circulaslderable height in the form of fine drops or sprayaud under the influence of the deflectors is apt to be driven by thewind more or less out of the sides of the tower. amount of water thus scattered and lost will depend upon the velocity of the wind, which if considerable will carry quite a large quantity of the spray with it. To prevent this loss of water and at the same time allow the netting is preferably fastened to the edges of the pans, which can readily be accomplished by nailing, as with nails t' i, into the wooden stifienin'g-strips H on the edges of the pans. This netting will allow air to pass freely through the tower, but it willcatch and arrest the spray whichmay be carried against the netting and prevent it from being blown away from the tower. The spray when thrown against the netting will accumulate in larger drops and run down the netting until it reaches the pans or falls down into the tank beneath the tower, and this action of the water in running comparatively slowly down the netting, which is kept cool by its direct contact with the outer air, will still further reduce the temperature of the water in its downward passage.

By means of my improvements I obtain and the water falling from a conby lateral escape of the spray without changing the efiectiveness of the tower in cooling the water.

-Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, i's- The combination, with the supportingframework of a water-cooling apparatus, of a plurality of spraying-pans arranged one above 15 the other, and supported by said framework,

each pan having its bottom provided on the under side with doubled portions forming inclined deflecting-flanges integral therewith, and also provided with perforations through said bottoms above the upper sides of said deflecting-flanges, and with wooden strips reinforcing the upper edges of said pans, and

guard-nettings in the spaces between said.

pans and attached thereto by fastenings driven into said wooden reinforcing-strips, substantiallyas described.
